Is it safe to eat spices and herbs out of the bottle?

They are probably safe to eat. I doubt they have much in the way of harmful bacteria. However, I don't imagine it would taste too nice. There is also a possibility that you will have more than your system can cope with (such as if the herbs may have a medicinal use or if they but a burden on the liver or kidneys.).

Prolly not. Some spices are toxic in high enough concentrations/quantities.

Are you a idiot
